That might have been the criticism, but the truth is that JA doesn't really look any different than a brown eyed brunette from Ireland. She easily "looked" the part.

Not to me. Her complexion didn't look remotely Irish. If anything, dyeing her hair blond brought out her skin tone even more by contrast.

The problem is Hispanic isn't a race. Hispanics can look like Chris Evans. And Alba's background is Mexican, Danish and French Canadian. Why single out the Mexican part?

Because they don't look related. I don't give a damn which ethnicity they are in real life, but they're supposed to be brother and sister, so they should look like brother and sister, and they didn't. Don't read anything more into it than that. I wouldn't care if one of them was Hispanic and the other not if they actually looked like they were siblings. Hell, I would've been perfectly happy if they'd cast both of them as black, or Chinese, or Pakistani, or anything, as long as they looked like they were closely related to one another. But they didn't. Not to me.
